A connecting device comprising an expanding sleeve and a conical nut; an assembly comprising at least one such connecting device

Abstract

The invention relates to a connecting device (26), adapted for holding assembled parts (22, 24), comprising: a screw (30), a nut (32) configured to screw onto the screw (30), a tubular body (34) and an expanding sleeve (36) positioned around the shank (38) of the screw (30) and interposed between the head (40) of the screw (30) and the nut (32), the tubular body (34), the expanding sleeve (36) and the nut (32) being rotationally locked relative to each other, the tubular body (34) comprising a portion configured to lock it in rotation or to allow it to pivot, the expanding sleeve (36) being configured to occupy a retracted state and an expanded state in which it has a greater cross-section than in the expanded state. retracted,the nut (32) comprising cross-sections dimensioned to cause the expanding sleeve (36) to move from the retracted state to the expanded state.
